Lub neej ntawm qhov tseeb LED uas tsim lub teeb yog ib feem txiav txim siab los ntawm kev ua haujlwm kub ntawm LED (LED hlws ris kub) xws li tias qhov kub ntawm qhov qis dua lub neej ntawm LED. Lwm qhov tseem ceeb cuam tshuam rau LED lub neej cuam tshuam nrog rau pem hauv ntej tam sim no uas tau hais tseg yog proportional rau lub ci ci ntawm LED. Feem ntau, rau pem hauv ntej tam sim no tsis yog ib qho teeb meem loj vim tias cov tuam txhab LED yuav qhia txog kev nyab xeeb kev ua haujlwm, txawm hais tias cov kab sab saud yuav tsum tau tsim kom muaj cua sov zoo dua. Yog hais tias lub LED khiav kub qis qis rau pem hauv ntej tam sim no tuaj yeem txuas lub neej ntawm LED nti, txawm hais tias feem ntau yog LED nti tau khaws cia txias nrog cov khoom siv hluav taws xob zoo (hauv qab 85 degree), lub sijhawm lub neej yuav tsis txawv ntau dhau.
L70 LED Lub neej expectancy
LED teeb qhov muag tsis tshua muaj kev puas tsuaj zoo li muaj cov khoom siv ua ntej. Thaum cov tuam txhab qhia txog lub neej ntawm LED lossis lub neej ntawm tag nrho LED teeb lub teeb hauv cov xuab moos lawv tau xa mus rau L70 cov ntaub ntawv uas sawv cev rau qhov kev kwv yees qhov tseeb ntawm lub sijhawm coj mus rau LED poob 30 feem pua ntawm nws qhov ci lossis txo qis rau 70 feem pua ntawm nws qhov ci ci qub, yog li L70. Qhov no feem ntau teev nyob rau hauv thaj tsam ntawm 30, 000 txog 40, 000 teev thiab feem ntau hu ua Lumen tu lossis Lumen depreciation.
Txawm li cas los xij, lub teeb ci LED yuav tsis poob tam sim ntawd tab sis txuas ntxiv tsim lub teeb zoo tshaj li L70 lub neej taw tes, txawm hais tias nyob rau ntawm qhov qis qis kom txog thaum lub teeb tsaus dhau los siv tau. Kev kwv yees qhia tias lub teeb LED yuav kav ntev txog 100, 000 teev lossis ntau dua ua ntej nws thaum kawg kaw. Hauv ntau daim ntawv thov uas yog "lub teeb rau lub neej"! Yog li ntawd, LED lub neej feem ntau yog ntev txaus thiab tsis tshua dhau los ua qhov teeb meem tshwj tsis yog thaum lub sijhawm ua haujlwm txuas ntxiv lossis kev ua haujlwm siab, uas raws li tau hais tuaj yeem tshwm sim los ntawm kev tsim tsis zoo.
Kev suav ntawm L70 Life Expectancy siv LM-80 cov ntaub ntawv xeem thiab TM-21 Extrapolation
Kev suav ntawm L70 LED lub neej taw tes yog qhov yooj yim tab sis lub sijhawm siv cov txheej txheem siv LM-80 cov ntaub ntawv xeem uas xav tau qhov ci ntsa iab lossis lumens kuaj ntawm ntau cov qauv LED ntawm peb qhov kub sib txawv, 55 degree, 85 degree thiab ib qho, thiab txiav txim siab qhov poob hauv lub teeb siv ntawm ntau lub sijhawm cov ntsiab lus ntau dua 6000 txog 8000 teev. Qhov kev sim yuav siv sijhawm yuav luag ib xyoos los ua.
Raws li kev sib tham, ib zaug peb muaj LM-80 cov ntaub ntawv xeem rau LED nti peb tuaj yeem ntxiv ntxiv siv TM-21 txoj kev uas yog qhov pib ua haujlwm thiab cov qauv kom paub tseeb L70 lub neej nyob rau hauv cov xuab moos ntawm LED nti thaum nws poob rau 70 feem pua ntawm nws cov zis.
